Abstract: 11,782. Ricketts, J. B. May 20. Refuse-consuming furnaces. - Consists of an incinerator or destructor for consuming domestic and like refuse in hotels, hospitals, &c. and adapted to store such refuse as it accumulates and comprises as its chief features a construction of grate which avoids direct exposure to the flames and is capable of easy dumping, means for allowing liquid to drain into an evaporating-pan, and means for effectually consuming noxious fumes. In its simplest form, the furnace comprises a receptacle 1 for garbage, closed at the lower end by a grate, beneath which is arranged a second grate 14 for a solid-fuel fire. The products of combustion from the fire pass partly through the garbage and partly through baffled flues 26 surrounding the container to a smoke and fume consuming chamber 23 at the upper end of the apparatus. The gases escaping from the container are deflected by a baffle-plate 29, and additional air for combustion is supplied through openings 28 from the air-heating space 16 between the intermediate and outer casings 12, 15. The walls of the container are inclined at their lower ends 4 towards the grate, and the grate sections 2 are in turn inclined towards a liquid-receptacle 3. The sections 2 and receptacle 3 are interconnected for simultaneous dumping. Garbage is fed into the container through a suitable opening closed by a hopper door. In a modified form for operating with gaseous fuel, the liquid-receptacle 3 is arranged some distance beneath the grate, and its place is taken by a gas-burner which is protected from the garbage by a ridge hood. The air supply to the space beneath the grate and to the passage 16 between the casings 12, 15 is controlled by a hit-and-miss slide interconnected for simultaneous operation with the gas-supply cock. The simple baffle-plate 29 may be replaced by an arched chamber 29<a>, Fig. 9, containing a Bunsen burner, the flames from which play through long slot-like orifices 46<a>. In another modification, Fig. 10, each grate section is of V-form, the inner arms forming a space in which is arranged the burner 33 with its protecting-hood 35. The portions a, b of each section are formed with narrow slots, while the portion 54 has broad openings through which the flames from the burner are directed. The portions a, 54, of the inner arms are set at an obtuse angle, as shown, and when the grate is in operative position, the portion 54 is approximately vertical. In a further modification, the grate is formed by a single section similar to those shown in Fig. 10, and the burner is arranged parallel to the front wall of the furnace, and is protected partly by the grate and partly by an overhang on the front wall of the refuse-container. A passage connecting the space beneath the grate with the secondary combustion chamber is formed at the back of the furnace and receives heated air from passages at the sides of the furnaces. The rear wall of the container is grooved to allow the ready descent of liquid and ascent of the gases from the burner.
